A06B-0503-B201 Fanuc AC Servo Motor Model 30 Brake

Most modern servomotors are designed and supplied around a dedicated controller module from the same manufacturer. Controllers may also be developed around microcontrollers, but this is rarely worth the time and trouble, compared to buying off-the-shelf. Incremental encoders are simpler, cheaper and work at faster speeds. Incremental systems, like stepper motors, often combine their inherent ability to measure intervals of rotation with a simple zero-position sensor to set their position at start-up.
